Rakuten Seimei Park Miyagi

Rakuten Mobile Park Miyagi, officially Miyagi Baseball Stadium, is a baseball stadium located in Miyaginohara Sports Park in Sendai, Miyagi Prefecture, Japan. The 30,508-seat ballpark is owned by the prefecture and operated by Rakuten, which has used it as the home field for the Tohoku Rakuten Golden Eagles of Nippon Professional Baseball since 2005. Its symmetrical playing surface is the only natural turf field in the Pacific League. An amusement park named Smile Glico Park is integrated into the stadium's left field seating and features a Ferris wheel.

Miyagi Stadium is the third-oldest NPB stadium and the oldest in the PL. It was built in 1950 to host countryside NPB games and amateur baseball. Lights were added to the ballpark in 1973 to accommodate night games and attract more professional games.
